Retrieving Data from a JavaScript Function Parameter

How is the parameter ‘Stored’ used to relay input field data into a JavaScript function? See the revised code sample:

<input type="button" id="btnSubmit" value="Send" onclick="processDetails('Stored');" />
document.getElementById('btnSubmit').addEventListener('click', function() {
    let firstName = document.getElementById('firstName').value;
    let lastName = document.getElementById('lastName').value;
    if (!firstName || !lastName) return;
});

function processDetails(parameter) {
    let userFirst = document.getElementById('firstName').value;
    let userLast = document.getElementById('lastName').value;
    let userData = [userFirst, userLast];
    NativeBridge.receive(userData);
}

Based on the provided code snippet, the parameter ‘Stored’ is simply a literal string that gets passed into the processDetails function, yet it is never actually used within that function. In my experience, this is a common scenario where a developer might have meant to pass dynamic content or a trigger value but never implemented it in the function logic. It is advisable to either remove unnecessary parameters or refactor the function to make use of them if they are intended to trigger different behaviors. This refinement not only clarifies intent but also reduces potential confusion during maintenance.

From a practical standpoint, the parameter as used in your code isn’t doing anything useful aside from being passed into the function. I’ve encountered similar cases in my own projects where a parameter is included, maybe as a placeholder for future code modifications, but then never utilized to process data. The function retrieves input values directly from DOM elements rather than using the parameter. In my view, it’s best practice to either remove such unused parameters to retain clarity or modify the function so that the parameter has an active role in the logic.

hey, i noticed the parameter is never really used so it can be removed or put to work. if its intended for future use, then implement it properly. otherwise, keeping it only adds confusion.
